Microjig is famous for clever shop aids, most developed by company founder, Henry Wang. Recently I had the chance to try out two of the company’s latest offerings: a push block and some clamps.

The Microjig GRR-Ripper 3D push block is the latest in Microjig’s family of push blocks. The Grr-rip clamp is a new work-holding design. They both offer lots of interesting features.

GRR-Ripper 3D push block
I’ve used lots of different push blocks from Microjig and other companies, as well as made my own push blocks from scrap wood. Frankly, some of the manufactured push blocks have more features than benefits. They are too complicated and require too many adjustments. I was pleased to see the GRR-Ripper 3D model is simple and straightforward.

With a comfortable and secure top handle, this push block has two narrow rubber-coated side legs and one wider adjustable leg in the middle. There is also an adjustable outrigger to help stabilize the push block. An accessory called the SafeRip Kit that came with my sample, adds rulers and a transparent cursor to make adjusting the center leg of the push block even easier.

Grr-rip clamps
These clamps combine the fast action of common one-handed squeeze-adjust clamps with a dovetail-shaped bar that fits in any worktable with a ½-inch dovetail slot for an instantquick-a ction vertical hold-down device. There are non-marring clamping surfaces and up to 150-pounds of clamping force.

How do they work?
With just two adjustments — the outrigger and the center leg — the GRR-Ripper 3D is fast and easy to use, adding a significant measure of safety in tablesaw ripping operations.

The Grr-rip clamps combine with dovetail slots for very secure work holding. You can easily add appropriate dovetail slots to sleds, fences, and other work fixtures or even workbenches to make use of these clamps all over your shop.

Microjig's new Grr-rip clamps won't be available until the fall, but the GRR-Ripper 3D push blocks are available now. You can learn more about these and other Microjig products at microjig.com.
